Saute. Heat the olive oil over medium-high heat in a small skillet. Add the onion and saute until translucent. Add the garlic and saute until fragrant. Turn off the heat.
Load the crock pot. Add the sauteed onion and garlic to a crock pot along with the chicken, black beans, tomatoes, green chilis, corn, enchilada sauce, chicken stock, cumin, smoked paprika, salt, and pepper.
Slow cook. Put the lid on the crock pot and cook on high for 4 hours (or on low for 7 hours).
Preheat the oven. When the soup is ~30 minutes away from being done, preheat the oven to 400°F and line a baking sheet with parchment paper.
Season. Toss the tortillas with olive oil and salt
Bake. Spread the seasoned tortilla strips in an even layer over the prepared baking sheet. Bake for 5 minutes and then toss with a pair of tongs. Bake for an additional 5 minutes or until crispy.
Shred. Transfer the chicken to a cutting board and shred it with two forks. Return the shredded chicken to the crock pot.
Season. Taste the soup and season with salt and pepper to taste (if needed).
Serve. Serve the soup hot, topped with cilantro and crunchy tortilla strips.
Notes
Variations & Optional Add-ins
Use crushed-up tortilla chips if you aren't up to making your own crispy tortilla strips.
Top the healthy chicken tortilla soup with fresh cilantro or your other favorite toppings.
Add a little tomato paste to make the soup thicker and bump up the tomato flavor.
Instead of diced tomatoes a can of rotel would be a great choice in its place.
Make this creamy by adding some half and half or heavy cream in at the end.
